402 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
En tOIIl., Sept. 1878, V. 1<», p. 17(i) says fchia Bpeoiea is double-brooded in the Southern 
United States. Packard (Boll. ?. U. 8. Entom. Comm., 1881, p. 113) figures the larva. 
Neumoegen (Papilio, Jan. 1882, v. 2, p. 18) states that this species usually emerges 
from the pupal state at about ."> p. in. : Brodie (op, tit.. May 1882, v. 2, p. 83), on the 
oontrary, states that the emergence normally takes place about lb a.m. Riley and 
Others state that the larva has !iv<- Stages, but Wailly (Hull. Soc. Accliui. France, May 
L882, s. 3, v. <>, i». 266-267) writes that it has six stages. Bro.lie (Papilio, Feb. 1882, 
v. 2, p. 35-33) gives a list of 49 species of plants belonging to 20 gener* on which the 
larva will feed: The genera are Tilia, Acer, Negundo, Praaat, Spiraa, Oratagm§ t Pj- 
rus, Amclauchicr, Hibes, Savibncus, Ulmus, Quercus, Fagua, Corylus, Carphntu, Betula, 
Ainu*, Salix, and Populus. From other authors the following genera are compiled : 
Herberts. Liriodendron, Syringa, Carya, Gleditschia, Rubus, Ceanothus, Ampdopsis, Ceph- 
alantlttts, Fraxinus, T'accinum, and Rosa. 
Larva. — Body very thick, cylindrical, enlarged at the two last thoracic and first 
abdominal segments, the segments moderately and evenly convex, not angular, 
sutures distinct. The head is almost wholly retractile within the prothoracic ring, 
the latter also partially retractile in the succeeding ring. 
Head of moderate size in proportion to the body, rounded, not so wide as the pro. 
thoracic segment; green with no markings. It is smaller and less rounded above 
than in T. polyphemus. Head and body green, the color of the upper side of the 
plum, birch, or oak leaf. Prothoracic segment with a slight transverse ridge in 
front, on which are four dorsal small light-blue warts and one larger tubercle on the 
side, in front of and a little lower than the prothoracic spiracle. On each of the 
three following segments is a pair of short, club-shaped reddish tubercles with black 
spines; these are succeeded along the abdomen by two rows of six subdorsal, much 
slenderer but fully as long, bright yellow tubercles, which have two or three black 
spines on the end. These two rows are terminated by a single bright yellow tubercle 
on the last spiracle-bearing segment (eighth abdominal), which is nearly twice as 
thick as the others. Two lateral widely-separated rows of slender, bright-blue, 
elongated tubercles, ending in two to four black spinules; these are slenderer than 
the dorsal yellow tubercles, and the two rows are far apart, the row of spiracles 
being between them ; the spiracles are pale glaucous green, surrounded by a very nar- 
row black rim. On the ninth segment is a transverse row of six pale bright cerulean 
blue tubercles. Thoracic and abdominal feet a little paler green than the body. 
Supra-anal plate triangular, large, but obtuse at the end. Length, 70 mm ; thickness, 
I4 mm . Providence, October 2. Described from a specimen found feeding on the 
cherry. 
32. Edema albifrons (Abbot and Smith). 
This common oak caterpillar has been found by Mr. Reed to fre- 
quently occur on the maple. (Can. Ent., xv, p. 204.) 
33. Forest tent caterpillar. 
Cli8iocampa sylvatica Harris. 
A colony of the worms uot fully fed were found June 6, collected iu 
a mass near the ground on the trunk of the maple at Brunswick, Me. ; 
at this time they were molting for the last time. (See Oak insects, p. 
117.) 
34. Homoptera lunata Drury. 
Order Lepidoptera ; family Noctaid.e. 
In the Canadian Entomologist (xiv, p. 130), Prof. G. H. French de- 
scribes the seven stages iu the life of the caterpillar of this fine large 
moth, which feeds, he states, on the maple and willow. The duration
